Somfy
TaHoma v2
TaHoma v2 is the previous generation Somfy box, superseded by the TaHoma switch but still in thousands of homes. It is worth knowing because Home Assistant supports it over the local API, so an older installation does not have to be replaced to get local control.
Protocols
The box that most European Somfy installs from the 2010s are built around. It wires to the router over Ethernet and holds the io-homecontrol and RTS pairings for the house, and Home Assistant reads it through the same Overkiz integration as the current hardware, cloud or local. Developer mode is unlocked the same way, by tapping the PIN seven times in the TaHoma app, after which the integration talks to the gateway PIN plus `.local:8443`. No longer sold, and Somfy documents a replacement procedure for moving a v2 installation onto a TaHoma switch, so budget a service visit rather than a like-for-like swap. Until that happens there is no functional reason to replace a working v2 for the sake of Home Assistant: the entities and the local API are the same.
Hardware availability
TaHoma switch is the current hub in both Europe and North America, in two regional variants: the European unit adds io-homecontrol to RTS and Zigbee, the North American unit is RTS and Zigbee only because io-homecontrol is not sold there. TaHoma v2 and the Connexoon boxes are no longer marketed, and Somfy’s own product page labels the Connexoon box discontinued, but both stay supported by Home Assistant and both still answer the local API. Somfy myLink is listed obsolete on the Somfy store. Motors are ordered through Somfy dealers and shade fabricators rather than retail, so several of the links below are manufacturer product pages rather than storefronts.
